MOSO 80W Driver DALI-2+D4I AstroDim 176–305V for LED Street Light

Why choose the MOSO 80W DALI-2 D4i AstroDim driver

Street lighting networks demand more than simple on/off switching. This MOSO driver combines DALI-2 certification with D4i compliance and built-in AstroDim functionality, meaning each luminaire can operate autonomously on a pre-programmed dimming schedule without any external controller, while remaining fully addressable when a DALI network is present. That combination reduces infrastructure cost and simplifies commissioning on both small and large installations.

• DALI-2 certified: Full bidirectional communication allows individual addressing, real-time status feedback and fault reporting from each street light on the network.
• D4i compliance: Standardised power interface between driver and luminaire enables plug-and-play integration with D4i-ready control nodes and sensors without additional wiring.
• AstroDim: An internal astronomical clock dims the luminaire automatically according to time-of-night profiles, eliminating the need for a central controller or photocell on every pole.
• Wide voltage range (176–305V): Handles supply fluctuations common in outdoor grid infrastructure across the EU without derating, protecting the luminaire and extending service life.

Where to use it

This driver is suited to new-build and retrofit street lighting projects on urban roads, residential streets, car parks, industrial access roads and cycle paths. It is equally appropriate for sports area perimeter lighting and any outdoor area luminaire where autonomous dimming schedules need to run independently of a central management system, or where a DALI-2 street lighting control network is being deployed.

What the specifications mean in practice

• 80W output: Matches the power envelope of mainstream LED street light modules, making this a direct working driver for mid-range road luminaires without oversizing or derating.
• DALI-2: The current certification standard ensures interoperability with any DALI-2 compliant controller or gateway, future-proofing the installation against system upgrades.
• D4i: Provides a standardised auxiliary 2W power supply for control nodes, removing the need for a separate power tap and simplifying luminaire head assembly.
• AstroDim: The driver calculates local sunrise and sunset times internally, so dimming profiles shift automatically with the seasons without manual reprogramming.
• 176–305V input: Covers the full range of European single-phase supply voltages including the elevated voltages found on rural or industrial distribution networks.

Installation and compatibility

The driver fits inside standard street light heads with a conventional wired connection to the LED module. DALI-2 signal wiring uses a standard two-core bus. AstroDim profiles are configured via DALI commands or a programming tool during commissioning.
